Structure & Working Principle of Bw250 Three-Cylinder Piston Triplex Mud Pump
BW250 portable mud pump machine is a horizontal three-cylinder reciprocating single-acting piston pump. The pump has two cylinder diameters and four-speed variables. The large cylinder liner is used for 1000-meter large-diameter drilling rigs, and the small cylinder liner is used for 1500-meter small-diameter drilling rigs.
The pressure of the mud pump
The pressure of the pump depends on the depth of the drilling hole, the resistance of flushing fluid (drilling fluid) through the channel, as well as the nature of the conveying drilling fluid. The deeper the drilling hole and the greater the pipeline resistance, the higher the pressure needed.
With the changes in drilling hole diameter and depth, the displacement of the pump can be adjusted accordingly. In the mud pump mechanism, the gearbox or hydraulic motor is equipped to adjust its speed and displacement. In order to accurately measure the changes in pressure and displacement, a flow meter and pressure gauge are installed in the mud pump.
Application of the mud pump
BW series drilling mud pump is widely used in mining, drilling, coal, railway, highway, water conservancy, hydropower, Bridges, high-rise buildings, and foundation reinforcement engineering.
